When you're dog bites, yell at her and lock her up in her cage. Leave her in there for ten minutes and totally ignore her which means no telling her to be quiet when she barks just act like shes not there. If you're dog doesn't learn by that, spank her but lightly and yell 'No'! If she walks away and ducks her head down, she won't do it fore a while but she will do it again. When you're dog is hyper, it is usual for you're dog to bite because she is crazy in the time. I hope this helps.
